Method for obtaining porous ceramics tablets hydroxyapatite and tricalcium phosphate for curing bone defects in patient, involves mixing reagents of pore-forming agent, where phosphate pore forming agent are stirred, dried and sintered

NOVELTY – The method involves mixing reagents of hydroxyapatite/tricalcium phosphate pore forming agent, where the reagents phosphate pore-forming agent are stirred, compressed, washed, dried and sintered. A simple mixture of hydroxyapatite, tricalcium phosphate and a pore-forming agent i.e. saccharose, are provided, where the mixture of the hydroxyapatite/ tricalcium phosphate are specified in a ratio of mass from 1 and 99%, preferably 50% in mass. Quantity of the saccharose is varied according to volume of mixture of the hydroxyapatite and the tricalcium phosphate. USE – Method for obtaining porous ceramics tablets hydroxyapatite and tricalcium phosphate for curing bone defects in a patient. ADVANTAGE – The method ensures that the tablets are provided with maltulose porosity, so that neoformation of bones can be avoided, thus reducing bone defects caused by diseases or accidents in an easy manner. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is also included for a ceramic porous tablet. DESCRIPTION OF DRAWING(S) – The drawing shows a flow diagram illustrating a method for obtaining porous ceramics tablets.'(Drawing includes non-English language text)’
